Abstract (en)
[origin: WO0102177A1] A micro electro-mechanical device for ink jet printers has a liquid-containing nozzle chamber (12) and a movable component (20, 22) [thermal actuator structure] extending into the chamber. Difficulties exist in sealing such a device against movement of the liquid through an opening through which the actuator extends. This difficulty is resolved by shaping the actuator (20, 22) in such a way as to induce the formation and maintenance between the wall of the chamber and the actuator (20, 22). The first portion (20) of the actuator is located substantially within the nozzle chamber and the second portion (22) is located outside the nozzle chamber. The stem portion (26) of the second portion (22) is connected by a shoulder (28) to an end portion (30) of the first actuator portion (20). A meniscus formed between the step (26) and the outer edges (36) forms a seal preventing liquid from inside the chamber to leak through.
